The Director General of CERN, Rolf Heuer, calls this exciting new discovery “a remarkable achievement.”

(Heuer) “I think we have a success today, we have a discovery. We have discovered a new particle, a boson. Most probably a Higgs boson, but we have to find out which kind of Higgs boson this is. Does it have the properties which we expect from the Standard Model?”

The Standard Model is a theory of everything. Scientists believe the Higgs boson could answer the long-standing question of why the fundamental building blocks of matter have mass. The scientists say the discovery of this new boson could be a key to the structure of the universe.
